Fig. 9 is a sectional view taken on line 9-9 of Fig. 8.

The portable seat, in accordance with the iirst form of the presentinvention illustrated in Figs. 1 to 6, inclusive, has a rigid, ilatframe preferably of aluminum or other light metal or alloy and a cover16 of exible material such as fabric or thermoplastic sheeting.

Frame 15 is U-shaped wit-h two spaced upright members 17 and 18 having across member 19 joining them together at one end. The cross member 19may be formed integral with the upright members or may be secured byscrews 20 at Ithe upper end of the frame to the upper ends of theupright members 17 and 18.

2,792,875 Patented May 21, 1957 Clamps 21 and 22, or other securingmeans are provided at `the free ends of the U-shaped frame 15 on theupright members 17 and 18, respectively, removably to secure the framerigidly to a` bench 23 or other backless support. Clamps 21 and 22 areG-clamps with spaced arms 24 and 25 adapted to iit over a bench 23 orother backless support. Wing nut screws 26 extend through threadedopenings 27 in the lower arms 24 of Ithe C- clamps 21 and 22 rigidly tohold the frame 15 to the bench. The at frame 15 has a front face orsurface 28 and thev C-clamps 21 and 22 extend from the front face orsurface 27 of the frame at the lower ends of the upright members 17 and18.

Cover 16 is generally tubular in construction with closed ends 29 and 30and having a central hinge portion 31 and two end portions 32 and 33.End portion 32 has a` pad-holding pocket 34 with a mouth or pocketopening 35 adjacent the hinge portion and in the rear side 36 of thecover. The hinge portion 31 is in the front side 37 of Vthe cover 16.

End portion 33 of cover 16V has a pad-holding pocket 38 withl a mouth orpocket opening 39 adjacent the hinge portion 31 and in the rear side 36of the cover 16. The two pocket openings 35 and 39 are opposed when thecover end` porftions 32 and 33 are hanging in alignment as indicated indot-dash outline in Fig. 4. The pocket openings 35 and 39 are providedby a central opening in the rear side 36 of the tubular cover 16.

End portion 32 of cover' 16 is the back forming half and is adaptedremovably and frictionally to iit over the frame' 15 covering the crossmember 19 and' substantially allA of the upright members 17 and 18except the clamps 21 and 22.

A resilient pad 40,` preferably of foam rubber, is provided for thepocket 34 of the end portion 32 of cover I6. Pad 40 is shaped as shownin Fig. 6 removably and frictionally to t snug inside the pocket 34 andnot to fall' out.

Frame 50 has spaced upright members 55 with a cross member 56 at theupper ends thereof connecting them. The lower ends 57 of upright members55 are connected by hinges 58 to the upper end 59 of a C-clamp 60. Theclamp 60 may be a continuation of the upright members, these membersbeing hinged adjacent to and spaced from the hinges.

The clamp 60 has an upper arm 61 which forms the ICC tached collapsibleand folding legs 62, V63, 64 and 65 with braces 66, 67, 68 and 69respectively, to hold the legs in extended position. The `lower arms 70of clamp 60`contain wing nut headed screws'71 extending through threadedopenings 72 so that the seat may be used on a bench or other backlessstructure if desired lin place of using the legs 62, 63, 64 and 65. y
